Hi Jenny.
May I, in a gentle and friendly fashion, suggest that Google is the researcher's friend?
First I typed "troopship adelaide australia 18 april 1942". The very first link had the phrase
Disembarkation order for the troopship Dorset. 18 April 1942. Then I googled "troopship Dorset". The very first link goes to a page of
World War II Sea War, Vol 5: Air Raid Pearl Harbor. This Is Not a Drill By Donald A Bertke, Gordon Smith, et al. The page has tables of ship movements, in particular:
Quote:
29 March 1942
Troopship DORSET (10,624 grt) arrived at Aden from Suez, Egypt with 940 personnel for Australia. She departed later in the day for Fremantle Australia.
I doubt that the Dorset called at Sydney first, but leave that research to you as a class exercise
